MSENSE® VAM

Use vibroacoustics to analyze the heartbeat of your tap-changer

On-load tap-changers are among the most important and critical components of power transformers. It is therefore crucial for grid operators, to be able to determine their condition at any time. Based on our experience from over 20 years of tap-changer monitoring, we have developed a unique online diagnostic tool: MSENSE® VAM.
VAM stands for vibroacoustic measurement, and this device can be used universally for on-load tap-changers of all types and brands. 

Good to know: Our service goes even further. Our VAM ANALYSIS SERVICE offers a detailed report with recommendations and actions.

Your Advantages at a Glance

  1. Indicates faults at an early stage that are not detected with other online monitoring methods

  2. The self-learning algorithm guarantees easy integration into any transformer and can be used for a wide range of tap-changers from other manufacturers.

  3. Integrated system solution through flexible combination options with other ETOS® modules

  4. VAM ANALYSIS SERVICE provides probable causes and clear instructions for action
